The present disclosure relates to proteases having an amino acid sequence with at least about 70% sequence identity to the amino acid sequence given in SEQ ID NO:2, over the entire length thereof, and comprising an amino acid substitution at at least one of the positions P9, Q62, D101, N130, G166, N187, 5216, N238 or Q271, based in each case on the numbering according to SEQ ID NO:2. The present disclosure also relates to the production and use thereof. Such proteases exhibit very good stability, in particular storage stability, while at the same time having a good cleaning performance.
